MOTOR FOR CLOCKS.

SPECEFICATION forming part of Letters Patent No. 510,754, dated December 12, 1893.

Application filed April 4, 1893 Serial No. 468.963, (No model.)

To aZZ whom, it 7-way concern:

Be it known that I, Srcrsnunn 13. Wear- MANN, of New York city, in the county and State of New York, have invented a new and Improved Motor for Clock or Like Mechanism, of which the following is a full, clear, and exact description.

My invention relates to a motor of the grav ty type, especially adapted for the propuls1on of clock mechanism and equivalent trains of gearing, and the object of the invention is to impart regular and uninten rupted movement to clock works orlike trains of gearing without employing the aid of a spring, spring drums, or like factors.

A further object of the invention is to provide a mechanism for imparting movement to the clock mechanism or works for any desired length of time, which device may be exceedingly simple,durable and economic in its construction, and which after its power has been spent may be almost instantly placed in position to again assert its power.

The invention consists in the novel construction and combination of. the several parts, as will be hereinafter fully set forth and pointed ontin the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of a clock illustrating the improved motor as applied thereto. Fig. 2 is a vertical section taken essentially on the line 22 of Fig. 1; and Fig. 3 is a rear elevation of the clock a portion of the back being broken away.

As heretofore stated, when clock work or clock mechanism is actuated by the motor there is no necessity of the employment of a spring, spring drum or like article, but the motor is geared with the driving master or drum wheel A of the clock movement with which the drum would be connected,or upon which the spring, if employed, would act. Below the clock mechanism a shaft 10, is journaled in any suitable bearing, and this shaft carries a pinion 11 fast upon it, and likewisea gear 12 of proper size, which gear meshes with a driving wheel or drum wheel A of the clock mechanism. The pinion 11, meshes with a large gear or master motor wheel 13. This wheel is preferably loosely mounted upon a shaft 14:,journaled below the upper shaft 10. The master motor wheel 18, is provided with a clutch face 15 upon its hub, adapted to engage with a clutch 16, splined or otherwise held to slide upon the shaft 14 yet turn with it, the clutch being held in engagement with the clutch face of the master motor gear 14, by means of a spring 17 or its equivalent. motor is used to run a clock, all the mechanism above described may be concealed within the clock casing B, as shown in the drawings, but the driving shaft 14, will extend beyond the back of the clock. The clock illustrated in the drawings is a pendulum clock,and the pendulum is designated as 18. The drive shaft 14, is rotated or revolved through the medium of a gravity lever 19, one end of which lever is securely attached to the drive shaft, and any approved means may be employed to effect this attachment. In the drawings a disk 20, is attached to the rear end of the drive shaft, the said disk being channeled to receive the lower end of the lever 19, and the lever and disk are connected through the medium of screws or like fastening devices. The lever is of such length that it extends, when in an upper position, some distance beyond the top of the clock mechanism, but the length of the lever is varied according to the character of the clock or mechanism to be run. The outer or free end of the lever is weighted, which may be done by enlarging the outer end of the lever, or by locating thereon a weight 21, which may be of an ornamental character; and the weight, when attached, may be either rigidly secured to the lever or may be adjustably connected therewith. A stop pin 22, is located upon the rear of the casing of the movement, and the pin is so placed that when the lever is carried to an upper position it will be at more or less of an angle to a perpendicular line.

The length of time that the clock movement will run through the medium of the improved motor will be regulated by the diameter of the motor master gear 13 and the number of teeth carried thereby; and I de- In the event the w sire it to be distinctly understood that other gearing than that illustrated may be employed as a connecting medium between the master or drum wheel of the movement and the corresponding wheel of the motor.

Assuming the lever to be in an upper position,the weight at the outer end of the lever will cause the latter to gravitate downward. This downward movement will be slow owing to the resistance of the gearing, but the weight of the free end of the lever must necessarily be of greater power than the power of the resistance of the gearing interposed between the motor drive shaft and the driving or master wheel of the clock movement. As the lever moves downward the motor master wheel will be revolved and a similar movement will be imparted to all the gearing connected with it. Thus it will be observed that the lever applied in the manner above set forth takes the place of a spring and renders the running or driving mechanism of a clock movement exceedingly simple. Furthermore, a clock may be made to run for a week, a month or a number of years before the lever shall have reached its lowermost position, or a position in which it ceases to exert power upon the driving shaft. When the lever reaches such a position it may be instantly carried to operative position again, as all that is necessary is to carry the lever upward to an engagement with the stop pin 22, and the hands or any part of the clock mechanism will not be acted upon at that time, as the ratchet upon the drive shaft will slip by the ratchet face of the master driving gear of the motor.

It will be understood that this motor may be applied to any train of gearing that needs to be run for a length of time.

Having thus described my invention, I claim as new and desire to secure by Letters Patent '1. The combination with a clock or like 1novement,of a motor for operating the same, said motor, comprising a drive or master wheel mounted on a shaft independent of said movement, gearing connecting the master wheel to said movement, a weighted lever secured to the shaft of the master wheel, a spring actuated clutch mechanism between the lever and master wheel, said clutch mechanism being mounted on the shaft of the master wheel and held to revolve with said shaft and slide upon it, and a stop located in the path of the lever to limit its upward movement, as and for the purpose set forth.

2. The combination with a clock or like movement, of the gear wheel 12 mountedon a shaft 10, and meshing with the driving wheel of the movement, a pinion 11 mounted on the. same shaft and meshing with the master motor wheel 13 mounted loosely on shaft 14, the hub of the master wheel being provided with a clutch face 15, a spring actuated clutch 16 adapted to engage with the clutch face of the master wheel and held to revolve with the shaft and slide upon it and a gravity lever 19 secured at one end to the shaft of the master motor wheel as and for the purpose set'forth.
